The Preterist view: This camp is split as to whether it refers to Jerusalem or to Rome. Most see this as a declaration of praise for His faithful delivery, the omnipotent reign of God, and for the Church to get ready for Christ’s return, being prepared by faith in Him. This is demonstrated by the prostration of the twenty-four elders and the Hallelujahs, Praise the Lord, and roar. The marriage of the Lamb is seen as a declaration of the new covenant or epoch of grace in which we live as Christians. This is also a contrast or correlative to the divorce of the harlot and the fulfillment of His promise to be faithful. This also is seen as a declaration to the Church to prepare its people for its nuptials (discipleship), and to live worthy with the redemption that we have received.
The Futurist view: Most in this camp see this passage as a call of God to rejoice in the fall of the beast and Babylon! The marriage of the Lamb is seen as Israel being reunited to Christ and God’s relationship with the Jews restored and brought into the Christian Church. Others see this as figurative, solely the Church and its union with Christ. Most see this happening right after the rapture and the end of the tribulation, while others see this as the Church being friends of the Bridegroom from John 3:29. Some see this as the unsaved people, after the rapture, being offered salvation or the saints of all the church age past, present, and future. Some see the marriage of the Lamb and the marriage supper as two distinct feasts, ignoring Jewish wedding traditions and word meanings, saying one group is for the Jews and the other for Christians. Some go so far as to say the bridegroom is not Christ and the guests are not the Church, ignoring the rest of the counsel of Scripture. Testimony of Jesus is seen as the whole council of God, His Word and Spirit to the Church, and/or the call for the Church to be a good witness. Others take this as finding the key to Revelation, not from the proper understanding of Scripture, but from subjective analysis, from personal whims, and from sensational insights, while others who read the Bible see this as the redemptive work of Christ for the Church.
The Idealist view: They see this passage as the end of human time when Christ is about ready to return. The marriage of the Lamb is seen as the day of doom for the beast and its followers while the faithful are rewarded. The marriage is consummated as Christ takes the Church as His bride. The cost of the dowry was paid by Christ on the cross. The wedding guests are not only the people invited, they are also His bride, and the individual guests are collectively His Church. Fine linen is seen as the wedding clothes worn by the bride and groom, representing Christ and His purity and the call of purity and faithfulness to His Church. Testimony of Jesus is seen as a call to Christian leaders (prophets) to take the Word of God and the Spirit and put it in their mouths to be proclaimed to their church.
The Historicist view: They see this passage as a celebration of the fall of the papal system and the rise of the Reformed Church out of the Reformation (true believers in Christ). Halleluiah is also the celebration of the faithful Jews for being included in the Kingdom (because of the use of the Hebrew word Halleluiah instead of one of the many Greek equivalents). The marriage of the Lamb is seen as the beginning of the millennial reign of Christ, or the reign of the true reformed Church of Christ. Others see this as those in Christ receiving their salvation and rewards. The rejoicing is the growth of the Church, its adherence to the Bible and the fading of the oppression and manipulations of the Catholic Church. Do not do it given to John is seen as a reminder not to fall back into apostasy or manipulation as a church or Church universal. As a Church, we are the bride of Christ called to proclaim Him, not to worship what is false, traditions, saints, Mary, popes, angels, relics, and/or indulgences.
